@bravenel, I was able to get it to work with using a POST message instead of a GET message. I was worried about trying to format the JSON data, it always confuses me, but there was documentation on IFTTT on the format that they wanted. Thanks so much for your help!!
If anyone finds this post in the future and is curious, the format for the JSON data for IFTTT webhooks is:
Substitute each %VALUE#% with a global variable or a direct value. Copy the whole thing along with the braces (curly brackets). You can only pass 3 values per webcall.
